Gov. Terry Branstad says the state has certified a portion of Iowa Army Ammunition Plant near Burlington as a project-ready industrial development site.

A 153-acre plot of land within the 19,000-acre federally owned military installation has been certified by the Iowa Economic Development Authority through its Iowa Certified Site Program.

It's the 12th site in Iowa to be certified as project-ready.

Branstad says certifying sites is fast growing trend in the site selection business. To get certified developers work with local officials, utility companies and consultants to ensure the site has no problems and is ready for development.

Congress passed legislation allowing leases on the land for up to 50 years.

On the ammunition plant portion of the property workers assemble and pack tank and artillery ammunition and missile warheads.
